The chemical standard used as a basis for the quantity of a mole is the carbon-12. Thus, the answer is letter D. By definition a mole is the number of atoms that would compose 12 g of the carbon-12. The reason for choosing such is that carbon is plentiful and not too hard to make isotropically pure.
Electrons ruminate around the nucleus in particular circular path known as orbit called shell.
Electronic configuration is the dispense of electrons.
Electronic configuration is also known as electronic structure.
Also termed as spatial methodize.
More than one orbital in the electron shell is known as subshell, they have similar energy level.
In Electronic configuration there are four shell present namely k,l,m,n and there are 4 sub-shell namely s,p,d,f.
As we know that every subshell fills gradually s max 2 electrons p - 6 , d - 10 and f - 14.
So,
According to questions,
Thge element has configuration 1s2 2s2 2p4 hence 8 electrons.
